The first case is a 59-year-old man who had left flank pain and nausea. KUB, excretory urograms and CT scan showed a left ureteral stone at the ureterovesical junction associated with spontaneous rupture of the left renal pelvis. Percutaneous nephrostomy was performed. The ureteral stone was spontaneously discharged on the 4th postoperative day and extravasation of contrast medium from the left renal pelvis disappeared. The second case is a 42-year-old man who was admitted with bilateral flank pain, nausea and vomiting. KUB and excretory urograms showed bilateral hydronephrosis due to small bilateral ureteral stones. Serum BUN and creatinine had risen to 41 and 5.1 mg/dl, respectively, on the day after admission. Percutaneous nephrostomy to the left kidney was performed. BUN and creatinine were normalized immediately and the bilateral ureteral stones were spontaneously discharged by the 9th postoperative day. After the nephrostomy catheters were removed, no complications occurred in either case and KUB and excretory urograms showed normal findings.

Fifty-three symptomatic adults with autosomal dominant polycystic kidney disease were studied retrospectively for a mean follow-up of 12 years (range 10 months to 33 years). Diagnosis was confirmed by either x-ray, ultrasound, laparotomy, or autopsy. Commonest presenting clinical findings were flank pain (30%), hypertension (21%), symptomatic urinary tract infection (UTI) (19%), gross hematuria (19%), and palpable masses (15%). A total of nine patients (17%) progressed to end-stage renal disease. Change in renal function measured using the reciprocal of plasma creatinine plotted against time was linear for each individual patient with a maximum functional decline of 0.7 mg/dL/yr (slope = -0.07). Past the age of sixty renal failure was uncommon. Easily controlled hypertension developed in 64% attended by mild retinopathy. UTIs were common (53%), often recurrent (61%), precipitated by instrumentation in 6 of 14 patients (43%), leading to death in two (33%). Renal calculi were extremely common (34%) and had no defined metabolic cause. The presence of hematuria (64%), gross or microscopic, bore no relationship to the decline in renal function. Pregnancy was normal in these patients with no increase in fetal or maternal morbidity or mortality. We conclude the following: Renal functional deterioration is linear, less than previously reported, and bears no relationship to hematuria. Hypertension is common, easily treated, and causes minor end-organ damage. Renal calculi are frequent. Urinary tract instrumentation often induces infection with considerable morbidity and mortality and must be avoided. Pregnancy is not contraindicated if renal function is normal. The prognosis for survival in this disease is better than previously reported.

A series of 70 pyonephrotic kidneys drained by percutaneous nephrostomy tube was examined to evaluate the contribution of radiologic imaging to the diagnosis of pyonephrosis and to assess the diagnostic and therapeutic role of drainage by percutaneous nephrostomy catheter. The diagnosis of pyonephrosis is suspected when the clinical symptoms of fever and flank pain are combined with the radiologic evidence of obstruction to the urinary tract. Sonography gives a prompt diagnosis of hydronephrosis, and needle puncture of the kidney yields pus and establishes the presence of pyonephrosis. A percutaneous nephrostomy catheter is then inserted and serves for initial drainage of infected urine and for evaluation of residual kidney function before definitive surgery. The nephrostomy catheter is used for diagnostic nephrostograms, ureteral perfusions, therapeutic dissolution of stones, and indefinite drainage of the kidney. In 10 azotemic patients, the blood urea nitrogen and serum creatinine values returned to normal levels after antibiotic therapy and nephrostomy drainage of infection. Long-term evaluation of residual renal function by means of an excretory urogram or a renogram was available in another 26 patients and 25 of them showed function of the previously pyonephrotic kidney.

A previously healthy 44-year-old man with well-documented normotension had a sudden onset of left flank pain and delayed onset of constitutional symptoms, hematuria, and elevations of lactic dehydrogenase, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, and creatinine levels. Angiography revealed unilateral renal artery fibromuscular dysplasia with dissection and infarction. In the year since, he has remained well and normotensive without therapy. The literature is reviewed.

Between August 1982 and May 1988, 503 patients underwent construction of a continent ileal reservoir (Kock pouch) for cutaneous urinary diversion at our university. Stenosis of the afferent antireflux valve resulted in upper urinary tract obstruction in 11 patients (2%). In addition, 2 patients underwent Kock pouch diversion elsewhere and upon referral to our institution they had afferent valve stenosis. To date 13 patients have been identified with this problem. Hydronephrosis was present in 100% of the functional kidneys in these patients. Radiographs of the Kock pouch were uniformly normal without evidence of reflux or other pathological condition. The most common presenting symptom was flank pain in 7 patients (54%) and the most common presenting sign was creatinine elevation above baseline in 7 (54%). Infections recurred with or without sepsis in 5 patients (38%). Ureteroileal anastomotic strictures were not present in any patient. The interval from creation of the Kock pouch to the diagnosis of stenosis ranged from 2 to 75 months (mean 39). All patients underwent endoscopic evaluation of the Kock pouch confirming stenosis of the afferent antireflux valve, and subsequent mechanical dilation of the stenotic valve. Dilation procedures were repeated in 6 patients (46%), 4 of whom subsequently required open surgical revision of the afferent valve. Of these patients 3 are clinically stable and 1 died of the primary malignancy. The remaining 2 patients are clinically and radiographically stable after multiple dilations. Of the 7 patients (54%) requiring only a single dilation 6 are clinically stable and 1 died of the primary malignancy. Stenosis of the afferent antireflux valve of the Kock pouch, previously unreported to our knowledge, is a rare late complication leading to flank pain, hydronephrosis, recurrent infection and elevation of serum creatinine levels. Approximately 50% of the patients respond to a single dilation of the nipple valve. However, most patients who require repeat dilation will need open surgical revision.

We describe an unusual complication of acute pyelonephritis in a 45-year-old diabetic female. She was admitted to our hospital due to fever and flank pain which had developed 10 days earlier. Urinalysis showed many WBC and urine culture revealed Escherichia coli. After adequate antibiotic treatment, clinical symptoms abated but renal failure and leukocyturia persisted. Abdominal CT showed bilateral focal bacterial nephritis and renal biopsy disclosed chronic granulomatous interstitial nephritis. On the 80th hospital day she was discharged with a serum creatinine of 299 mumol/l. In the outpatient clinic, renal dysfunction and leukocyturia persisted up to 1 year. In conclusion, this case raises the possibility of a chronic interstitial process of acute pyelonephritis.

Pulmonary lymphangioleiomyomatosis (LAM) is a rare disorder that affects women and can lead to serious respiratory impairment. Since Bourneville's tuberous sclerosis (TS) was first reported, the striking similarities between the two entities have led many to believe that LAM is a forme fruste of TS. This is suggested by reports that angiomyolipomas, rare tumours in themselves, are reported in 40-80% of TS patients and occur in 15-30% of LAM patients. A retrospective chart review was conducted of 14 patients that presented to our institution with a diagnosis of LAM. We sought to document the clinical manifestations, particularly the incidence and location of extrathoracic tumours, in order to further support the hypothesis that LAM is a forme fruste of TS. Twelve patients had premenopausal onset of symptoms and two postmenopausal. The diagnosis was confirmed histologically (n = 12) and/or by computed tomography (CT) scan of the thorax (n = 12). Imaging investigations revealed extrathoracic tumours in 12 of 14 patients (86%). Eight of the 14 patients (57%) had renal tumours consistent with angiomyolipomas (bilateral in five patients). Only one patient had renal symptoms (flank pain and haematuria). All had normal serum creatinine, one had a reduced creatinine clearance. Extrathoracic nonrenal tumours were discovered in the pancreas, adrenals and uterus, findings previously unreported in LAM. In summary, the incidence of extrathoracic tumours in lymphangioleiomyomatosis patients is much higher than previously reported in the literature. This increased association supports the theory that lymphangioleiomyomatosis and tuberous sclerosis represent part of a spectrum of a similar disease process.

The objectives of our study were to (1) assess the outcomes resulting from the use of sonography in patients referred to our institution's ultrasound laboratory for an elevated serum creatinine level and (2) determine relevant clinical parameters in these patients to better triage them for sonography. We retrospectively identified and determined outcomes of 60 patients (20 women, 40 men; mean age, 61 years; range, 33 to 100 years) referred for sonographic evaluation because of an increased serum creatinine level (> or = 1.3 mg/dL). Ultrasound findings (hydronephrosis, renal size, and echogenicity) were correlated with clinical outcomes. Twenty-one patients (35%) had hydronephrosis, with 14 of these patients confirmed to be obstructed and five not obstructed. Two were indeterminate for obstruction. Eight of 14 obstructed patients were successfully treated. All obstructed patients had a suggestive history for obstruction with at least one of the following: pelvic mass (n = 9), stone disease (n = 4), or flank pain (n = 1). Only 2 of 44 patients, who were not obstructed, had any of these parameters (statistically significant difference, P < 0.0001). Thirty of the patients, who were not obstructed, had more likely alternative causes for renal failure, with sonography having no effect on patient management. Renal size and echogenicity had little effect on patient management. Sonography was efficacious in guiding management in patients with a suggestive history for obstruction (eg, pelvic mass, stone disease, or flank pain) but not in most patients who had no suggestive history and other more likely causes for renal failure.

A case of significant proteinuria occurred as a result of bilateral renal vein thrombosis secondary to dehydration, which resolved after treatment with urokinase. The patient developed nausea and vomiting from viral gastroenteritis with subsequent volume contraction. He later noted the onset of aching lower abdominal and flank pain. On admission, he was noted to have a serum creatinine of 1.7 mg/dL, and 4+ proteinuria on urinalysis. A 24-hour urine collection showed 2.34 g protein. A renal venogram showed bilateral renal vein thrombosis (RVT) without involvement of the inferior vena cava. Therapy was initiated with heparin at 1,000 U/hr, followed by intravenous (IV) urokinase, 4,400 U/kg bolus, followed by 4,400 U/kg/hr with continuous infusion for 12 hours. A repeat renal venogram done at this time showed partial resolution of thrombosis bilaterally. A second 12-hour infusion of urokinase at 5,000 U/kg/hr was performed; at this time, the patient reported resolution of his flank and abdominal pain. A repeat 24-hour urine collection showed 60 mg protein with a normal creatinine clearance. Levels of antithrombin III, protein C, and protein S were all normal. A renal biopsy was performed and showed normal histology on light, immunofluorescent, and electron microscopic evaluation. The patient has done well on no therapy and has had no recurrence of thrombosis or proteinuria after 2.5 years. This is a US government work. There are no restrictions on its use.

A 57-year-old male patient was admitted to our hospital for left flank pain and a slight increase in serum creatinine. He had left hydronephrosis and extrinsic stenosis of left lower ureter shown by intravenous and retrograde pyelography. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a mass along the bilateral lower ureters, the left side of which was larger (5 x 3 x 4 cm). After surgical exploration and biopsy of the tumor the patient was diagnosed as having xanthogranulomatous inflammatory pseudotumor. No malignant findings were observed. Tumor size spontaneously decreased to 20% of the original size at 2 weeks after laparotomy. The patient underwent ureterolysis because of prolonged left hydronephrosis. Approximately 3 years after development of disease, hydronephrosis has improved and the pelvic tumor has almost diminished.
